Yeah to be clear the Fargate container hosting was always the vision for ECS, from the very first internal proposal to build this system. But its necessary to build something that keeps track of container state at scale first, and that is ECS. We built ECS so that it can keep track of container state both in Fargate and containers running on your own self managed EC2 hosts. This gives you the most flexibility if you have really specific needs for your container hosts that Fargate can't cover for you.
